Documented Viral Illness at the Time of Splenic Sequestration Does Not Affect the Odds of Recurrence in Children With Sickle Cell Disease

This retrospective study investigates the relationship between the presence of a documented viral infection in children with sickle cell disease during their first splenic sequestration crisis and their odds of recurrence. Forty-eight children were admitted to our hospital between 2008 and 2018 with a splenic sequestration crisis. Thirty-six had respiratory viral panels done on admission, 13 of whom were positive. Two additional children were diagnosed with parvovirus B19 infection by serology. The recurrence rate was 52% (17/33) for those deemed negative for viral illness compared with 33% (5/15) among those with a positive documented viral illness, which was not statistically different (P=0.35). HbSC genotype decreased, and reticulocytosis increased the odds of recurrence. Further research is needed to substantiate these findings.
